I think only passing an SMTP server value will do this. Besides make sure the machine, you are using to send CDO mails, are having SMTP settings done on it in IIS. I am also using such CDO functionality & initially I use to give those 3 parameters, "SendUsing", "SMTP Server", "SMTP Server Port" & it was working fine. But later our IT department migrated our mail server to Outlook 2007 & then we had to remove the other 2 parameters except "SMTP Serve".
Try doing this & let me know....
